These figures are for radiation absorbed by an anatomical model, not the total radiation emissions. A phone with a higher SAR may simply have a less effective radiation pattern, directing less energy into free space and more energy into the user.
- wlesieutre 8y agoIs that "into the user" as measured when holding it up next to your head and talking into it?
- jdietrich 8y agoYes. SAR testing uses a model of the head, with the phone held next to the ear. On a smartphone, you're essentially measuring the amount of energy coming out of the screen side of the device. When the device is being used handheld, this is effectively wasted energy, because most of it will be directed towards the sky rather than towards the horizon.
